How to Fix MSI Tomahawk MAX Catalina network problem

This mini-guide provides a structural approach to troubleshoot and fix the issue.

Prerequisites

  • Confirm your hardware specifications (CPU, GPU, Motherboard).
  • Ensure you have a bootable recovery USB and backup your EFI.

Fix Steps

  1. Verify your network controller model (Intel, Broadcom, Realtek).
  2. Ensure the correct kext (e.g., AirportItlwm or BrcmPatchRAM) is loaded in your config.
  3. Clear network interfaces and reset NVRAM if changes don't apply.

Verification

  • Reboot and verify if the functionality is restored and stable under typical usage.

Original Question:

Hello folks !

I installed catalina on my build but seems that the network driver doesn't work.

My build:

  • MSI Tomahawk MAX
  • Ryzen 5 3400G
  • Sapphire Radeon RX590 Nitro+ SE
  • G.Skill RipjawsV 16GB DDR4-3600MHz

My open core setup:

BOOT

  • BOOTx64.efi

OC/ACPI

  • SSDT-EC-USBX-DESKTOP.aml

OC/Drivers

  • HfsPlus.efi
  • OpenRuntime.efi

OC/Kexts

  • AppleALC.kext
  • Lilu.kext
  • RealtekRTL8111.kext
  • VirtualSMC.kext
  • WhateverGreen.kext

my Config.plist -> http://s000.tinyupload.com/index.php?file_id=44746693393743086684

I saw many examples for this motherboard and all of them use this network driver.

What i'm missing here ?

P.S.: The macOS boots but without network.
